For example:
If the ‘Energy Reduction Maintenance Settings (ERMS)’ optional protection function settings are active (with blue ERMS LED (A) is lit on the front face of the MicroLogic X control unit and Blue backlight (B)) and you start the firmware upgrade, you can see the both LED and backlight get turned off meaning that the ERMS optional protection settings are turned off during the firmware upgrade.
